The video demonstrates configuration of remote access IPSec VPN with Windows software client on Cisco router. We will look at both simple pre-shared key authentication as well as using client certificate. The client is placed behind a NAT router to demonstrate the significance of NAT Transparency, and compare it to raw IPSec and cTCP (IPSec over TCP). The video finishes off by showing how client can be allowed access to local subnet when a non-split tunnel is used.

- NAT Transparency (UDP 4500)
- cTCP aka IPSec over TCP

The video walks you through configuring site-to-site (L2L) IPSec VPN tunnel on Cisco routers using static Virtual Tunnel Interface (VTI). We will demonstrate VTI ability to support more than just unicast traffic, and how it offers many benefits similar to GRE tunnel but without the extra GRE overhead. In this lab, EIGRP is used as an example. In addition, we will point out VTI limitation to support non-IP protocol, in which case, we need to resort to GRE. MPLS is a good example and what we use to demonstrate in this lab.
Topic includes
- Static VTI
- Tunnel Interface IP Unnumbered
- MPLS
- GRE
